RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. PURPOSE: This phase I trial is studying the side effects and best dose of 17-N-allylamino-17-demethoxygeldanamycin in treating patients with refractory advanced solid tumors or hematologic cancers.
OBJECTIVES: * Determine the maximum tolerated dose of 17-N-allylamino-17-demethoxygeldanamycin (17-AAG) in patients with refractory or advanced solid tumors or hematologic malignancies. * Evaluate the effects of this drug on the expression of signaling proteins present on an individual patient's cancer at the start of treatment and, if possible, post treatment. OUTLINE: This is a two-phase, dose-escalation, multicenter study. Patients are stratified according to disease (chronic myelogenous leukemia \[CML\] or Philadelphia chromosome \[Ph\]+ acute lymphoblastic leukemia \[ALL\] vs solid tumor). Patients receive 17-N-allylamino-17-demethoxygeldanamycin (17-AAG) IV over 60-90 minutes twice weekly. Courses repeat every 12 weeks in the absence of disease progression (after at least 2 courses for CML or Ph+ ALL patients) or unacceptable toxicity. * Accelerated phase: Single patients receive escalating dose levels of 17-AAG until one patient experiences a first course grade 3 or greater toxicity or two different patients experience grade 2 toxicity during any course. * Standard phase: Cohorts of 3-6 patients in each stratum receive escalating doses of 17-AAG until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. PROJECTED ACCRUAL: Approximately 51 patients will be accrued for this study.
